voltage mixers/scalers that can take 10 V?

voltage mixers/scalers that can take 10 V?

2008-03-15 by cuari7

Hi,

Since the resurgence of another old icon, the Mighty Buchla, I have
wondered about the existence of mixers/scalers that could deal with
the higher voltage ranges that its modules work with, such as the
281e.
Buchla offers the 210e and the 256e, however, these are digital
mixing/attenuating devices that do not offer the luxury of fine, non-
stepped voltage scaling. I have tried to mix voltages from the 281e
into stock Doepfer mixers, and the output pegs out at +5 V. Also, for
reasons I can't explain, the Doaff cannot invert these voltages.

So the question begs: Can any of the Serge attenuators/mixers/scalers
deal with these higher voltages? I have owned many Serge panels in
the past (which unfortunately I ended up selling. Damn!!!!) and I
think they would only take up to +/-5 V.
If this is not the case (which I'm afraid of), then could/would our
good friends at STS (my main man Rex and his minions) make a, M-
module with these capabilities? I must point out to you that the size
of the front plates is perfectly compatible with the Buchla format,
not to mention the banana kinship between the two brands. This would
definitely make financial $en$e, I think, since the Buchla format is
becoming quite popular among synth geeks and, in fact, there are
other 3rd-party companies making some of their own modules Bookla-
compatible (f. example: Cynthia's Zeroscillator). Also, the "e"
version (or "Neo-Buchla") sorely lacks true analog scalers/inverters.

I hope this stirs interest in producers and consumers alike. I will
be happy to be your beta-tester, Rex!

what voltage range are we talking about? I just did a quick
measurement... it looks like the Serge can deal with voltages
in the range of +/- 11v, which is about right when you consider the
rails are +/- 12v.

Yes, the Serge full scale linear range is +/- 10v (20v p-p)for
Control Voltages, Audio signals and Gates.

Nominal operation levels are:
0- +5V CV & gates (blue & red jacks) +/- 2.5 v audio (black jacks)

With this, the Serge system can then mix (sum) multiple CVs and/or
Audio Signals together without entering non-linear operations.

As John P. measured, there is another +/- 1.5 volts in there, but we
like to keep that as an extra buffer area before hitting the 'rails'.

Dr. Diaz!

Que pasa'migo ...

say, I just tried to email you directly, but it came bouncing back
like a rubber ball (as did a second 'test' email).

Could you email me so I can get a current address for you?

I would be great to hear from you and find out all you've been up
tosince we last touch base.

my email is: sts7@...


Sincerely,

Harry & Rex

(I apologize to the rest of you for this personal post to an old
friend and client) - HT

========
I hope this stirs interest in producers and consumers alike. I
will be happy to be your beta-tester, Rex!

Aright, Jesus!

I'll email you straight away and we can catch up on things ...

Best, HT

Wrong list perhaps but doesn't the 255 do what you want?

Answer:

NO.

The 255 (which I own) is actually 8 lag processors with a bias voltage
each. You can use them as portamento generators or as attack/release
EG's (this is the most common application I have for it, feeding the Z
voltage from my Continuum so that there will be some release voltage
when I take my fingers off the touch surface).
It also gives you additional voltage in a pinch (if you need it to open
a filter, change the pitch of an oscillator, etc).
I love this module. It's the only totally-analog one in the current
Buchla catalog.
After speaking to Rex, it seems that the scaling processors and dual
processors he sells would do the trick.
It's great to know, especially now that they can be had in hal-panel
module sets.
